My research aims at understanding the high-temperature fate of the hydrothermal deep biosphere. I'm interested in the formation of organic molecules as a result of pyrolysis of microbial biomass (Archaeal and Bacterial) under various hydrothermal conditions, using both an experimental as well as a field approach. My field of interest also includes understanding the effects of fluid-rock interactions, magma degassing, sub-surface cooling and mixing of seawater on hydrothermal fluids using fluid geochemistry and thermodynamic modelling. I'm based at the Department of Earth Sciences and the Centre for Deep Sea Research .
